TMS570LC4357: TMS570LC4357, TMS320F28335

Hello,

1. Hercules MCU's focus on safety and performance. Hercules RMx series MCUs are certified by TÜV to be capable of achieving IEC 61508 SIL3, and TMS570 series MCUs (automotive-grade) are certified by TÜV to be capable of achieving IEC 61508 SIL3 and ISO 26262 ASIL D. 

Hercules MCUs are high performance Arm Cortex-R-based MCUs from 80 Mhz up to 330 MHz with intelligent peripherals. Hercules MCU’s provide on-chip diagnostics coverage required by safety standards while enabling a smaller software footprint in a hardware optimized solution which reduces safety system complexity.

• LockStep CPUs -- 1oo1D safety concept
• CPU built-In self-test (BIST) controller
• ECC on FLASH and RAM
• ECC calculation in CPU checks the interconnect
• Memory BIST on CPU and peripheral RAMs
• Clock and voltage monitoring
• Error signaling module with error pin

2. C2000's focus is on supporting control algorithms. The big applications are power converters, power line communication, industrial drives, and motor control.

3. TI's main dual-chip solution is "C2000+TMS570", which takes advantage of the real-time advantages of the C2000 in motor control and the features of the TMS570 in a functional safety solution. This solution is loved by more and more customers. The two-chip solution has a huge advantage in automotive electronic security.
